摘要

Inequalities characterizing differential operators

We show that under certain inequality assumptions an arbitrary linear operator \(D:C^\infty (\mathbb {R}) \rightarrow C(\mathbb {R})\) is a differential operator, for example, if D[f] is nonnegative in local minima of f.

期刊介绍： aequationes mathematicae is an international journal of pure and applied mathematics, which emphasizes functional equations, dynamical systems, iteration theory, combinatorics, and geometry. The journal publishes research papers, reports of meetings, and bibliographies. High quality survey articles are an especially welcome feature. In addition, summaries of recent developments and research in the field are published rapidly.
